Biography A.O.Ibhadon PhD CChem FRSC MIM SFHEA MSPE
Reader Catalysis & Reactor Engineering for Energy Generation and Chemical Synthesis
Visiting Professor, Panjab University, India

Dr Ibhadon graduated with a doctorate in Physical Polymer Chemistry from the University of Birmingham thanks to a Commonwealth Scholarship. PhD work (distinction in first year assessment), involved the mechanical properties and crystallization behaviour of semi-crystalline polymers. Work on crystallization after ‘partial melting’ was put into commercial exploitation in the ‘Thermoforming’ Operations at Metal Box (Oxon), enabling the manufacture of plastic products with enhanced fracture toughness, impact resistance as well as reduced environmental stress cracking. This results from this work also formed the basis of about eight articles published in the Journal of Applied Polymer Science, including articles such as ‘Crystallization Regimes in Semi-crystalline Polymers’, ‘Physical Ageing in Isotactic Polypropylene’ and ‘Strain hardening behaviour in Semicrystalline Polymers’
Employment as a postdoctoral research fellow, School of Chemical Engineering and Advanced Materials, Newcastle University and a lectureship appointment at the University of Hull, followed my PhD study at the University of Birmingham and developing my research in catalysis at the University of Hull.
Dr Ibhadon is a Reader in Catalysis and Reactor Engineering for Energy Generation and Chemical Synthesis at UoH, Senior Fellow, Higher Education Academy and a Fellow of the Royal Society of Chemistry (CChem FRSC) with research expertise in Catalysis and Advanced Materials. Dr Ibhadon has received £5,425,671.43 (as investigator and co-investigator) in research funding and is a co-founder of a Spin-Out Company between the UoH and the University of Warwick. Dr Ibhadon has published over 72 articles in leading journals in the area of Catalysis and Chemical Synthesis and made 84 conference presentations.
Catalysis, the focus of my research work, is the bedrock of manufacturing in the Chemical, Pharmaceutical and Allied Industries. The Chemical industry employs > 67% of EU workforce and contributes > £50BN to UK GDP. Catalysis is an internationally important and competitive arena. For example, catalysis driven Artificial Photosynthesis provides energy security and climate mitigation, enables Smart Cities and Sustainable Futures, while Catalysis driven Nitrogen Fixation ensures food security for > 4.5BN people by providing fertilizers for agriculture through the Haber Bosch Ammonia process; this process use heterogeneous catalyst materials that have an annual market turnover of $220BN. Thirdly, decarbonisation of energy systems and protection of our global ecosystems and bio-diversity, is only possible with catalyst materials as they will enable sustainable manufacturing, renewable energy production, and innovations in green technologies, and support for the Circular Economy while also providing millions of job opportunities, globally. Catalysis is a priority technology area for the UK via EPSRC/UKRI research portfolios and is the reason for UK Catalysis HUBs at Cardiff, Manchester and Bath Universities and other UK institutions.

Research Themes
1. New Generation of Renewable energy Technologies
We carry out research work on the decarbonisation of the energy system as this is required to enable the UK and other nations to meet their national determined contributions (NDC) as well as obligations set out in the Paris Climate Change Agreement. To achieve these objectives requires the ultimate replacement of fossil fuels with renewable alternatives that have the capability and flexibility for long-term and large-scale storage in new kind of energy storage compounds. In this regard, our work is focused mainly on the production, storage and transport of hydrogen from renewable routes. Due to its high energy density (about 3 times higher, on weight basis) than the energy density of conventional fuels, hydrogen (H2), is a clean and feasible alternative to carbon-based fuels and decarbonisation of the UK energy sectors, e.g. the transport sector, by switching to H2 fuel will not only help the UK Aviation meet its net-zero CO2 emissions target, it will also contribute to enabling the UK government to meet its targeted emission reduction obligations. This is the basis of our current five ‘live’ hydrogen based projects listed below.

2. CO2 utilization via conversion into fuels/renewable energy generation
CO2 utilization via conversion into fuels such as dimethyl ether (DME) or raw materials such as methanol using physical or chemical methods offers an approach to sustainably and economically abate and recycle CO2 and eliminate the economic liability and health & safety concerns associated with geological CO2 storage in carbon capture and storage (CCS) technology. Various technologies, including thermocatalysis, electrocatalysis, photocatalysis, and biochemical technology, can be used for this purpose. Of these, the solar-driven photo-catalytic process has proved to be a promising technology (Roy et al, ASC Nano, 2010, 4, 1259-1278). However, photo-catalytic technology has low conversion efficiency and low utilization of solar energy, which vary significantly from one technology to another. To tackle this challenge, a photo-catalytic system that can make efficient use of solar energy is the most desired development. Solar light absorption and electron transportation in conventional photocatalytic materials are difficult especially in single photocatalyst systems because: (a) semiconductor has a lower light absorption capability than phytochroms, although ionic doping and semiconductor coupling have been used to broaden the spectrum responsive range.
Recent research indicates that introducing disordering and defected surfaces can significantly increase light absorption (Chen et al, Science, 2011, 331. 746-750); (b) photo-catalytic systems are, unlike phytochroms, found in nature, in which the photo-generated electrons can be exploited by 100%. Compared to phytochroms, the electron transportation velocity of semiconductors is significantly lower, resulting in reduced separation efficiency of the photo-generating carriers. Although P/N hetero-junctions have been reported, the separation effect is not significant; (c) nanofabrication of photo-catalysts is an effective way to improve the photo-catalyst activity. Recent studies indicate that the photo-generating carriers can be effectively separated by the space confinement of nano-domains (Liu et al, J. Am. Chem. Soc., 2010, 132 14385-14387).
3. Photoelectrochemical CO2 reduction and H2O splitting
The photoelectrochemical reduction of CO2 competes with water reduction in aqueous media, i.e. H2 generation and the direct photo reduction is a challenge because CO2 is thermodynamically stable, showing a high energy barrier that impedes its activation and conversion in a multistep and complicated reaction pathway. For this reason, the conversion efficiency and reaction selectivity are largely compromised. The main CO2 reduction products are C1 (CO, CH4, CH3OH, CH2O, and HCOOH) and C2 (C2H4, C2H5OH, and CH3COOH), which are more desirable for applications in energy storage and transportation and as fuels because of their higher energy density and value. Electrochemical reduction allows the production of C1 with > 95 Faradaic efficiency, C2 with 60 % FE and C3 products with 8 %. The main advantage of a PEC reactor compared to a photocatalytic device is that its compartmentalized design allows for the separation of reduction and oxidation products. PEC reactor design for CO2 reduction is limited, however, the designs proposed for electrochemical CO2 reduction can be adopted and these are based on a cathode electrocatalyst immobilized in a gas diffusion layer, which overcomes the limitations of low CO2 concentration at the cathode interface. We use selective ion-exchange membrane to separate the anolyte and catholyte and surface modification to improve photoelectrode efficiency and stability
